Panasonic FV-0510VS1 WhisperValue Bath Fan, 50-80-100 CFM

The Panasonic WhisperValue Exhaust Fan FV-0510VS1 is incredibly quiet—you barely notice it’s running. It moves air well and feels like a big step up in quality compared to typical fans. It really helped elevate the overall feel of our bathroom remodel. Solid, reliable, and absolutely worth it.

What a big improvement over the cheap fans of years past. Really quiet and does the job. This is our third bathroom install for these fans. It’s always best to find a YouTube video as the directions are a bit confusing. This fan was made to fit in a 2 x 4 wall thus the oval exhaust hole. Instead of spending $20 for the premade adapters which may not fit, buy a galvanized 4” x 3” reducer and gently oval the 4” side with your hands. Use tape for galvanized or aluminum to secure it to the neck on the fan.

This fan is impressively quiet while still moving a lot of air. It makes a huge difference in clearing steam from the bathroom after showers without being loud or distracting. The slim design made installation straightforward and it fits perfectly even in a smaller space. Build quality feels solid and it runs smoothly without rattling. I am very happy with this purchase and would recommend it to anyone looking for an efficient and nearly silent bathroom fan.

This is a great fan and moves air very well with less noise than common fans that have a name starting with "B". A UL Listed fan was an absolute requirement. Lots of low profile fans on the market that do not have a safety certification. However, Panasonic is missing out on ceiling-side installation as a replacement fan. I was able to remove the fan and the section that holds the duct/electrical junction box from the housing. It would have been possible to reconnect the duct/electrical section once the housing was inserted from the ceiling side.....but the attachment point was misaligned by the thickness of the drywall, so I had to install from the attic side anyway. If the housing was 5/8" higher to offset the drywall thickness, the unit would still fit a 3-1/2" low profile space, but would be installed through the ceiling side rather than on the attic side. One review states they were able to install from the ceiling side, but the version I received would not work this way. Also, it would be better to provide a way to secure the fan housing from inside the room rather than the attic. The support arm provided is a challenge to install in tight spaces in an attic. I realize this would require retooling at the factory, but I would have selected a UL Listed low-profile fan that installed on the ceiling side over any others - if it was available. This one works nicely, but could be easier to install with some design changes.

Have two, one in each bathroom. Work great, adjustable fan speed and not noisy. Cover removes easily for cleaning as I vacuum the cover and every few months same for dust from the fan, our home has a lot so just to keep it well maintained.

Easy install, runs very quietly, does a great job sucking out the moisture out of the room from showers. Wish it was a little noisier to help conceal “bathroom noises” but better than being too noisy I suppose!

I like it being extra quiet.

The fan was larger than the one it replaced but not hard to open up ceiling to fit. Looks cleaner than the old one but it takes a few minutes to get up to full speed.

When turn on, it need 2 seconds to start, but the whole process it soundless. Even when I set the fan at maximum speed, I can only hear the wind on the vent, not from the fan. Extremely happy with it. Installed without issue. If the manufacturer give 1/2 inch cable connector and 3 wago wire nut inside the juntion box, it would be excellent.

After having to do more monkeying with drywall then I like enlarging a hole overhead with the requisite detritus in my eyeballs I finally got to squeeze the bejeezus out of very old 4" pipe and got this fan in. I had to take it all apart to sleeve the smaller housing with the opening and the electrical portion in place, pop in a couple screws, suture up the melding of the pipes with foil tape and snap in the larger housing, replace the fan guts with three screws and plug in tge electrical quick connect.. I only have it affixed on two sides but seems solid. I omitted the internal flap on this unit as it seemed to significantly reduce air flow and the exit duct already has a flap. On 50 setting in a 45 sq ft bathroom there is sufficient airflow and no discernible noise. Pretty great.

Due to the nature of my ceilings in my bathroom, a ceiling mounted vent fan was not an option. So I planned on wall mounting a ceiling fan but couldn't find anything that would fit in a 4" wall cavity. My friend who owns a contracting company told me about this fan and how it has a smaller profile. I have to say it fit perfectly with no hassle at all. The availability to select 50, 80, or 100 CFMs is a great feature given that there aren't many low profile vent fans out there. The noise levels at 50 and 80 are very quiet. However, at 100 as you can imagine it gets a little louder. My wife and I actually decided to set it to 100 CFM because 50 and 80 were too quiet. The noise of the fan offers some... "privacy" when using the bathroom. Thankfully, to change the CFM is extremely easy, simply remove the cover and flick a switch. The general install was straightforward, particularly if you are handy. A few screws secure it to the stud, wiring is as basic as it gets, and the cover leaves lots of room for error when drywalling around it. My only slight concern would be the shape of the duct. I used zip-ties along with aluminum duct tape as you have to bend the ducting to fit the low profile oval shape. I understand that this feature must exist to fit the 4" space, so I can't complain too much. Overall, if you require a vent fan that can be used in tight spaces, this is a great option.

The 70 sq.ft. bathroom in our house had a 70 CFM Broan installed which was quite loud, but more worrying was the amount of moisture on the ceiling and running down the walls after a shower. Bought this one based on the reviews and the selectable CFM’s. It installed fairly easy since it all comes apart, just had to cut a bigger hole attach the duct and wiring, snap it back together and screw it to the joist with some extra wood support I installed for rigidity. I set it at 80 CFM and its much quieter than the previous fan which was 4 sones. More importantly there is no more moisture collecting on the ceiling and walls!

Great fan, works great, easy to install, low noise and adjustable fan speeds. Happy with the purchase I would recomemd.
